[0002] The present invention relates to an improved cleaning composition that includes a
cationic biocide. The cleaning composition can be used alone, in combination with
one or more other cleaning compositions, and/or in combination towel, cloth, rag,
sponge, mop, squeegee, and the like.
BACKGROUND OF THE INVENTION
[0003] Many types of cleaning compositions have been developed to clean various types of
products and/or surfaces. Some of these cleaning compositions included one or more
compounds to disinfect, sanitize, and/or sterilize the product and/or surface. Acids
and alcohols have been traditionally added to cleaning solutions as the principal
biocide of the cleaning solution. The present invention relates to an improved cleaning
composition having that includes at least one cationic biocides such as, but not limited
to, biguanide compounds and/or quaternary ammonium salts ("quats") as the anti-microbial
active. The cleaning composition can include other traditional anti-microbial actives
such as, but not limited to, one or more acids and/or alcohols. The cleaning composition
is envisioned as being used in a wide variety of applications. As can be appreciated,
the additives in the cleaning composition that are used in combination with the cationic
biocide as the anti-microbial active may vary depending on the particular application
of the cleaning composition.
[0004] Cleaning wipes are a relatively recent concept that has gained wide public acceptance,
especially in the area of infant care products. Infant care wipes commonly include
inverse emulsions (i.e. water-in-liquid). Cleaning wipes have also included waxes
to polish and clean furniture and/or other metal, plastic and/or wood surfaces. Cleaning
wipes have further included soaps and/or detergents to clean an individual's hands,
countertops, floors, appliances, and/or the like. Cleaning wipes have also included
ammonia to clean glass surfaces. Alcohol and various other biocides have been included
on cleaning wipes to disinfect a variety of surfaces.
[0005] One type of biocide that has been used in cleaning wipes is quats. Liquid cleaners
applied to cleaning wipes typically include relatively large amounts of quat. These
cleaning wipes are typicallyused on hard surfaces such as floors, countertops, glass
surfaces, sinks, toilets, appliances, and/or the like. Although quats are excellent
biocides, quats can cause skin irritation when used in too high of concentrations.
In addition, only about 50% of the quat is released from the wipe when the wipe is
applied to a surface, thus added quat is included in the liquid cleaner to ensure
that the desired amount of quat transfers to the cleaned surface. Other biocides such
as biguanide compounds also have a low release rate from the wipe. Since the quat
and/or biguanide compound is typically one of the higher cost components of the cleaner,
the larger quat and/or biguanide concentrations used in the liquid cleaner translates
into higher product costs. There have been various attempts to develop liquid cleaners
having improved quat release from the cleaning wipes. Some cleaning formulations use
a high weight percentage of isopropyl alcohol to promote quat release from the cleaning
wipe. It has been observed that isopropyl alcohol in amounts of over about 12% can
improve the quat release from the wipe. The use of isopropyl alcohol is also beneficial
in that the alcohol has its own antimicrobial properties and co st substantially less
than quats. Although the use of isopropyl alcohol in the cleaning formulation improves
quat release from the wipe, a substantial amount of quat still remains on the cleaning
wipe after use. In addition, local, state and/or federal governments have begun to
promulgate regulations on the amount of isopropyl alcohol that can be used in cleaners.
Indeed, in California, regulations have been proposed to regulate the use of cleaners
containing over 4-5 weight percent isopropyl alcohol. As a result, cleaners having
high concentrations of isopropyl alcohol may be less preferred.
[0006] Quats also tend to leave residues and/or cause streaking after being applied to various
surfaces. The residue and streaking problems are of great concern to consumers since
the visual appearance of the cleaned surface functions as a visual indicator of the
effectiveness of the cleaner. Consumers also judge the cleaning effectiveness of the
cleaner by touching the cleaned surface. Sticky surfaces typically indicate to the
consumer that the surface has not been effectively cleaned. Cleaning formulations
that tend to leave residues and/or cause streaking tend to produce a less shiny, thus
a visually perceived less clean surface, and further tend to leave a sticky surface.
This is especially true with mop and wet wipe applications, where such compositions
are left to dry on the surface without rinsing. As a result, the consumer perceives
that the cleaned surface has not be effectively cleaned irrespective of the fact the
surface may have been properly cleaned and disinfected. Liquid cleaners having a high
quat content are also subject to various local, state and/or federal regulations due
to the toxicity of the quat in high concentrations.
[0007] Various types of biocides are also used to disinfect, sanitize, and/or sterilize
tools and/or equipment. Such biocides are commonly used in the medical field. Biocides
such as quats and biguanide compounds have typically not been used because of their
cost. Typically alcohols are used as the disinfectant. However, the use of alcohol
has come under more federal, state and local regulation, thus interest in the use
of other biocides has gained interest in recent years.
[0008] Biocides are also used to disinfect, sanitize, and/or sterilize areas that have been
exposed to infectious biological agents (e.g. anthrax, small pox). Presently, biocides
such as quats and biguanide compounds have not been used for such applications.
[0009] In view of the present state of the art of cleaning compositions, there is a demand
for an improved cleaning composition that can be used in a variety of applications
to disinfect, sanitize, and/or sterilize surfaces without leaving undesired residues
and/or streaking on the cleaned surface, without one or more components overly absorbing
and/or adsorbing into the cleaned surface, and/or which cleaning composition is cost
effective to use.
SUMMARY OF THE INVENTION
[0010] The present invention is related to an improved cleaning composition that includes
a cationic biocide. The improved cleaning composition is generally a liquid cleaner;
however, the improved cleaning composition may be in an aerosol, solid or semi-solid
form. The improved cleaning composition can be used by itself or combined with other
cleaning formulations. The improved cleaning composition can be loaded onto an absorbent
and/or absorbent material, and/or can be used separately from an absorbent and/or
absorbent material. The absorbent and/or absorbent material includes, but is not limited
to, cleaning wipes, cloths, sponges (e.g., cellulose, synthetic, etc.), paper towels,
napkins, rags, mop heads, cleaning pads, towels, brooms, other absorbent cleaning
tools, and/or the like. In one embodiment of the present invention, the improved cleaning
composition is applied to a surface to be cleaned prior to exposing the improved cleaning
composition to an absorbent and/or adsorbent material. In such applications, the improved
cleaning composition is not pre-loaded onto an absorbent and/or adsorbent material,
but instead is applied by the user to a surface to be cleaned and then wiped up by
the absorbent and/or adsorbent material. As can be appreciated, the absorbent and/or
adsorbent material can include some improved cleaning composition prior to wiping
the surface on which the improved cleaning composition is pre-applied. In another
and/or alternative embodiment of the present invention, the improved cleaning composition
is pre-applied to the absorbent and/or absorbent material for ease of use by the consumer.
The improved cleaning composition can be packaged to be used alone or in combination
with other cleaners and/or absorbent or adsorbent materials. The improved cleaning
composition is typically formulated to clean hard surfaces such as, but not limited
to, counter tops; however, the improved cleaning composition has much broader applications
and be used as a clean glass cleaner; appliance cleaner; floor cleaner; rug cleaner;
area disinfect, sanitizer, and/or sterilizer; and/or the like. As used herein, the
term "hard surfaces" includes, but is not limited to, bathroom surfaces (e.g., floor,
tub, shower, mirror, toilet, bidet, bathroom fixtures, etc.), kitchen surfaces (e.g.,
countertops, stove, oven, range, sink, refrigerator, microwave, appliances, tables,
chairs, cabinets, drawers, floors, etc.), furniture surfaces (e.g., tables, chairs,
sofas, love seats; benches, beds, stools, armoires, chests, dressers, display cabinets,
clocks, buffet, shades, shutters, entertainment centers, arm rails, lamps, banisters,
libraries, cabinets, desks, doors, shelves, couches, beds, carts, pianos, statues
and other art, mirrors, racks, fans, light fixtures, pool table, ping pong table,
soccertable, card table, etc.), statues, windows, window ledges, tools, utility devices
(e.g., telephones, radios, t.v., stereo equipment, CD and DVD players, analog and
digital sound devices, palm computers, laptop computers, desktop and tower computers,
computer monitors, etc.), automobiles (e.g., interior and exterior surfaces), bicycles,
snowmobiles, motorcycles, off-road-vebicles, yard equipment, farm equipment, washing
equipment (e.g., power washers, etc.), painting equipment (e.g., electric and air
powered painting equipment, etc.), medical and/or dental equipment, marine equipment
(e.g., sail boats, power boats, rafts, sail board, canoe, row boats, etc.), toys,
writing implements, watches, framed pictures or paintings, books, and/or the like.
The improved cleaning composition can also be used in a variety of industrial and
institutional applications. As used herein, the terms "industrial" and "institutional"
shall mean the fields of use which include, but are not limited to, contract (e.g.,
professional) cleaning and disinfecting, retail facilities cleaning and disinfecting,
industrial/manufacturing facilities cleaning and disinfecting, office cleaning and
disinfecting services, hotel/restaurant/entertainment cleaning and disinfecting, health
care (e.g., hospitals, urgent care facilities, clinics, nursing homes, medical/dental
offices, laboratories) facilities cleaning and disinfecting, educational facilities
cleaning and disinfecting, recreational (e.g., arenas, coliseums, resorts, halls,
stadiums, cruise lines, arcades, convention centers, museums, theaters, clubs, family
entertainment complexes (e.g., indoor and/or outdoor), marinas, parks) facilities
cleaning and disinfecting, food service facilities cleaning and disinfecting, governmental
facilities cleaning and disinfecting, public transportation facilities (e.g., airports,
airlines, cabs, buses, trains, subways, boats, ports, and their associated properties)
cleaning and disinfecting. The improved cleaning composition can be in concentrated
form or unconcentrated form (e.g., ready to use form). When the improved cleaning
composition is not first impregnated on an absorbent or adsorbent material, the improved
cleaning composition can be dispensed and/or sprayed as liquid from a container, as
an aerosol from an aerosol container, or as a crystal, powder, paste, or otherwise
semi-solid or solid form from a container. The improved cleaning composition can be
used as a disinfectant, sanitizer, and/or sterilizer. As used herein, the term "disinfect"
shall mean the elimination of many or all pathogenic microorganisms on surfaces with
the exception of bacterial endospores. As used herein, the term "sanitize" shall mean
the reduction of contaminants in the inanimate environment to levels considered safe
according to public health ordinance, or that reduces the bacterial population by
significant numbers where public health requirements have not been established. An
at least 99% reduction in bacterial population within a 24 hour time period is deemed
"significant." As used herein, the term "sterilize" shall mean the substantially complete
elimination or destruction of all forms of microbial life and which is authorized
under the applicable regulatory laws to make legal claims as a "Sterilant" or to have
sterilizing properties or qualities.
[0011] In one aspect ofthe present invention, the absorbent and/or absorbent material can
be at least partially impregnated with the improved cleaning composition. When the
improved cleaning composition is at least partially loaded or impregnated onto the
absorbent and/or absorbent material, the improved cleaning composition is formulated
to have a viscosity that allows such loading. Typically, the viscosity of the improved
cleaning composition is less than about 1000 centipoise ("cps") when the improved
cleaning composition is at least partially loaded or impregnated onto an absorbent
and/or absorbent material. The viscosity of the improved cleaning composition can
be greater than 1000 cps when the improved cleaning composition is used separately
from an absorbent and/or absorbent material, and/or is not to be preloaded onto an
absorbent and/or absorbent material.
[0012] In another and/or alternative aspect of the present invention, the cleaning wipe
onto which the improved cleaning composition is loaded at least partially includes
an absorbent and/or adsorbent material. In one embodiment, the cleaning wipe includes,
but is not limited to, a woven and/or a nonwoven material. In one aspect of this embodiment,
the nonwoven material includes, but is not limited to, nonwoven, fibrous sheet materials.
In another and/or alternative aspect of this embodiment, the nonwoven material includes,
but is not limited to, meltblown, coform, air-laid, spun bond, wet laid, bonded-carded
web materials, and/or hydroentangled (also known as spunlaced) materials. In still
another and/or alternative aspect of this embodiment, the woven material includes,
but is not limited to, cotton fibers, cotton/nylon blends and/or other textiles. In
another and/or alternative embodiment, the cleaning wipe includes a sponge and/or
sponge-like material. In one aspect of this embodiment, the sponge and/or sponge-like
material includes, but is not limited to, regenerated cellulose and/or polyurethane
foams. In still another and/or alternative embodiment, the cleaning wipe includes,
but is not limited to, wood pulp, a blend of wood pulp, and/or synthetic fibers. In
one aspect of this embodiment, the synthetic fibers include, but are not limited to,
polyester, rayon, nylon, polypropylene, polyethylene, and/or cellulose polymers. In
still another and/or alternative embodiment, the cleaning wipe includes a binder.
In yet another and/or alternative embodiment, the absorbent and/or adsorbent material
is part of a single or multiple layer cleaning pad. The cleaning pad can be used individually
and/or in combination with a mop and/or other cleaning device. In one aspect of this
embodiment, the cleaning pad has an absorbent capacity, when measured under a confining
pressure of about 0.09 psi after about 20 minutes, of at least about 1g deionized
water per gram of the cleaning pad, typically at least about 5g deionized water per
gram of the cleaning pad, and more typically at least about 10g deionized water per
gram of the cleaning pad. In another and/or alternative aspect of this embodiment,
the cleaning pad can have a total fluid capacity (of deionized water) of at least
about 100g; however, pads having a total fluid capacity of less than about 100g are
within the scope of the invention even though such cleaning pads are typically not
as well suited for cleaning large areas. In still another and/or alternative aspect
of this embodiment, there can be an absorbent layer on and/or in the cleaning pad
which serves to retain fluid and soil absorbed by the cleaning pad during use. The
absorbent layer typically includes at least one layer, and typically comprises multiple
layers which are designed to provide the cleaning pad with multiple planar surfaces.
In still yet another and/or altemative embodiment, cleaning wipe or cleaning pad can
include a superabsorbent material. As used herein, the term "superabsorbent material"
means any absorbent material having a g/g capacity for water of at least about 15
g/g, when measured under a confining pressure of about 0.3 psi. Representative superabsorbent
materials include, but are not limited to, water insoluble, water- swellable superabsorbent
gelling polymers. The superabsorbent gelling polymers useful in the present invention
can have a size, shape and/or morphology varying over a wide range. These polymers
can be in the form of particles that do not have a large ratio of greatest dimension
to smallest dimension (e.g., granules, flakes, pulverulents, inter-particle aggregates,
interparticle crosslinked aggregates, and the like), and/or the polymers can be in
the form of fibers, sheets, films, foams, laminates, and the like. The use of superabsorbent
gelling polymers in fibrous form provides the benefit of providing enhanced retention
of the superabsorbent material, relative to particles, during the cleaning process.
Superabsorbent gelling polymers useful in the present invention include, but are not
limited to, a variety of water- insoluble, but water-swellable polymers capable of
absorbing large quantities of fluids. Such polymeric materials are also commonly referred
to as "hydrocolloids", and can include, but are not limited to, polysaccharides such
as carboxymethyl starch, carboxymethyl cellulose, and/or hydroxypropyl cellulose;
nonionic types such as polyvinyl alcohol, and/or polyvinyl ethers; cationic types
such as polyvinyl pyridine, polyvinyl morpholine, N, -dimethylaminoethyl and/or N,
- diethylaminopropyl acrylates and/or methacrylates, and/or the respective quaternary
salts thereof. In one aspect of this embodiment, the superabsorbent gelling polymers
typically include carboxyl groups. These polymers include, but are not limited to,
hydrolyzed starch-acrylonitrile graft copolymers, partially neutralized hydrolyzed
starch- acrylonitrile graft copolymers, starch-acrylic acid graft copolymers, partially
neutralized starch- acrylic acid graft copolymers, saponified vinyl acetate-acrylic
ester copolymers, hydrolyzed acrylonitrile or acrylamide copolymers, slightly network
crosslinked polymers of any of the foregoing copolymers, partially neutralized polyacrylic
acid, and/or slightly network crosslinked polymers of partially neutralized polyacrylic
acid. These polymers can be used either solely or in the form of a mixture of two
or more different polymers. In another and/or alternative aspect of this embodiment,
the polymer materials used in making the superabsorbent gelling polymers typically
are slightly network crosslinked polymers of partially neutralized polyacrylic acids
and starch derivatives thereof. One nonlimiting example is hydrogel-forming absorbent
polymers that comprise from about 50 to about 95%, typically about 75%, neutralized,
slightly network crosslinked, polyacrylic acid. In still another and/or alternative
aspect of this embodiment, the superabsorbent material can be or include polymeric,
hydrophilic absorbent foams that are obtained by polymerizing a high internal phase
water-in-oil emulsion (commonly referred to as HIPEs). These foams are readily tailored
to provide varying physical properties (e.g., pare size, capillary suction, density,
etc.) that affect fluid handling ability. As such, these materials are particularly
useful, either alone or in combination with other such foams and/or with fibrous structures,
in providing the overall capacity required by superabsorbent material. In still yet
another and/or alternative aspect of this embodiment, the absorbent layer comprises
at least about 5% by weight of the absorbent layer, typically at least about 15%,
more typically at least about 20%, still more typically at least about 25%. In a further
embodiment, the cleaning wipe or cleaning pad can include chemically stiffened cellulosic
fibers. As used herein, the term "chemically stiffened cellulosic fibers" means cellulosic
fibers that have been stiffened by chemical means to increase the stiffness of the
fibers under dry and/or aqueous conditions. Such means can include, but is not limited
to, the addition of a chemical stiffening agent that coats and/or impregnates the
fibers. Such means can also and/or alternatively include the stiffening of the fibers
by altering the chemical structure (e.g., crosslinking polymer chains). In one aspect
of this embodiment, where the fibers are at least partially used as the absorbent
and/or adsorbent layer (or a constituent component thereof), the fibers can be combined
with a thermoplastic material. Upon melting, at least a portion of this thermoplastic
material can migrate to the intersections of the fibers, typically due to interfiber
capillary gradients. These intersections can become bond sites for the thermoplastic
material. When cooled, the thermoplastic materials at these intersections solidify
to form the bond sites that can hold the matrix and/or web of fibers together in each
of the respective layers. This can be beneficial in providing additional overall integrity
to the cleaning pad or cleaning wipe. Thermoplastic materials useful in the present
invention can be in any of a variety of forms including, but are not limited to, particulates
and/or fibers. Suitable thermoplastic materials can be made from any then-noplastic
polymer that can be melted at temperatures that will not extensively damage the fibers
that comprise the primary web or matrix of each layer. Generally, the melting point
of the thermoplastic material will be less than about 190°C, and typically between
about 75°C and about 175°C; however, other temperature ranges can be used. In any
event, the melting point ofthe thermoplastic material should be no lower than the
temperature at which the thermally bonded absorbent structures, when used in the cleaning
pads or cleaning wipes, are likely to be stored. In still a further and/or alternative
embodiment ofthe present invention, the cleaning wipes and/or pads can have an attachment
layer that allows the wipe and/or pad to be connected to an implement's handle or
the support head of various implements. The attachment layer is used in those embodiments
where the absorbent and/or adsorbent layer is not suitable for attaching the wipe
and/or pad to the support head of the handle. The attachment layer can also function
as a mechanism to inhibit or prevent fluid flow through the top surface (e. g., the
handle-contacting surface) of the cleaning wipe and/or pad, and/or can provide enhanced
integrity of the wipe and/or pad. In one aspect of this embodiment, the attachment
layer can consist of a mono-layer or a multi-layer structure. In another and/or alternative
aspect of this embodiment, the attachment layer can comprise a surface which is capable
of being mechanically attached to the handle's support head by use of a hook and loop
system. In one specific design, the attachment layer can comprise at least one surface
which is mechanically attachable to hooks that are affixed to the bottom surface of
the handle's support head. In a further and/or alternative embodiment, the liquid
loading capacity of the cleaning wipe or pad is sufficient to retain the desired amount
of improved cleaning composition on the cleaning wipe or pad. In one aspect of this
embodiment, the liquid loading capacity of the cleaning wipe or pad is at least about
10% of the dry weight of the cleaning wipe or pad. In another and/or alternative aspect
of this embodiment, the liquid loading capacity of the cleaning wipe or pad is about
50%-1000% of the dry weight of the cleaning wipe or pad. This loading capacity is
expressed as loading ½ to 10 times the weight (or, more accurately, the mass) of the
dry cleaning wipe or pad. In still another and/or alternative aspect of this embodiment,
the liquid loading capacity of the cleaning wipe or pad is about 200%-800% of the
dry weight of the cleaning wipe or pad. In yet another and/or alternative aspect of
this embodiment, the liquid loading capacity of the cleaning wipe or pad is about
250%-500% of the dry weight of the cleaning wipe or pad. In still yet another and/or
alternative aspect of this embodiment, the liquid loading capacity of the cleaning
wipe or pad is about 300%-450% of the dry weight of the cleaning wipe or pad. In still
a further and/or alternative embodiment, the improved cleaning composition is impregnated,
dosed, loaded, metered, and/or otherwise dispensed onto the cleaning wipe or pad.
The loading of the cleaning wipe or pad can be accomplished in several ways including,
but not limited to, treating each individual wipe or pad with a discrete amount of
improved cleaning composition, mass treating a continuous web of cleaning wipes with
the improved cleaning composition, soaking the entire web of cleaning wipes in the
improved cleaning composition, spraying the improved cleaning composition in a stationary
or moving web of cleaning wipes, and/or impregnating a stack of individually cut and
sized cleaning wipes or pad in a container and/or a dispenser. In yet a further and/or
alternative embodiment, the cleaning wipe or pad has a density of about 0.01-1,000
grams per square meter (referred to as "basis weight"). In one aspect of this embodiment,
the cleaning wipe or pad has a density of about 25-120 grams/m
2. In still yet a further and/or alternative embodiment, the cleaning wipe or pad is
produced as a sheet or web which is cut, die-cut or otherwise sized into the desired
appropriate shape and size. In another and/or alternative embodiment, the cleaning
wipe or pad has a wet tensile strength of at least about 25-250 Newton/m. In one aspect
of this embodiment, the cleaning wipe or pad has a wet tensile strength of about 25-250
Newton/m. In another and/or alternative aspect of this embodiment, the cleaning wipe
or pad has a wet tensile strength of about 75-170 Newton/m. Manufacturers of cleaning
wipes that can be used in the present invention include, but are not limited to, Kimberly-Clark,
E.I. Du Pont de Nemours and Company, Dexter, American Nonwovens, James River; BBA
Nonwoven, and PGI. Specific, nonlimiting examples of cleaning wipes from these manufacturers

[0013] In another and/or alternative aspect of the present invention, the cleaning wipe
or pad can be individually sealed with a heat-sealable and/or glueable thermoplastic
overwrap such as, but not limited to, polyethylene, Mylar and the like. In one embodiment,
the cleaning wipes or pads are packaged as numerous, individual sheets or pads which
are at least partially, impregnated with the improved cleaning composition ofthe present
invention. In another and/or alternative embodiment, the cleaning wipes are at least
partially formed as a continuous web during the manufacturing process and loaded into
a dispenser such as, but not limited to, a canister with a closure or a tub with closure.
The closure is at least partially used to seal the loaded cleaning wipes from the
external environment and/or prevent premature volatilization of the components of
the improved cleaning composition. In one aspect of this embodiment, the dispenser
includes a plastic such as, but not limited to, high density polyethylene, polypropylene,
polycarbonate, polyethylene pterethalate (PET),' polyvinyl chloride (PVC), and/or
other rigid plastic. In another aspect and/or alternative of this embodiment, the
continuous web of cleaning wipes is at least partially threaded through an opening
in the top of the dispenser. In still another and/or alternative aspect of this embodiment,
the dispenser includes a severing arrangement to cut at least a portion of the cleaning
wipe after being at least partially removed from the dispenser. The severing arrangement
can include, but is not limited to, a knife blade, serrated edge, and/or the like.
In still yet another and/or alternative aspect of this embodiment, the continuous
web of cleaning wipes can be scored, folded, segmented, and/or partially cut into
uniform and/or non-uniform sizes, and/or lengths. In a further and/or alternative
aspect of this embodiment, the cleaning wipes can be interleafed so that the removal
of one cleaning wipe advances the next in the opening of the dispenser.
[0014] In yet another and/or alternative aspect of the present invention, a kit is provided
for cleaning which kit includes the improved cleaning composition of the present invention.
The kit can have an assembly of one or more units, either packaged together or separately.
For example, the kit can include cleaning pads and/or wipes, and a container of the
improved cleaning composition. A second example is a kit with cleaning pads and/or
wipes, implement and a container ofthe improved cleaning composition. A third example
is a kit with a refill (concentrated or unconcentrated), a container of ready to use
improved cleaning composition, and cleaning pads and/or wipes that include a superabsorbent
material. In one embodiment, the implement that includes a cleaning pad and/or wipe
that includes a superabsorbent material, and when used with the improved cleaning
composition provides effective cleaning and good particulate soil removal. In one
aspect of this embodiment, the cleaning pad and/or wipe is a disposable and/or does
notrequire rinsing. In another and/or alternative embodiment, the cleaning pad and/or
wipe is detachably mounted on the implement. In one aspect of this embodiment, the
cleaning pad and/or wipe can be removed and replaced by another cleaning pad and/or
wipe. This is especially useful, when the cleaning pad and/or wipe is excessively
soiled. The cleaning pad and/or wipe can be removed and replaced with a fresh cleaning
pad and/or wipe. In still another and/or alternative aspect of this embodiment, the
implement includes a dosing device. The dosing device at least partially delivers
the improved cleaning composition to the surface to be cleaned and/or applies at least
a portion of the improved cleaning composition on the cleaning pad and/or wipe. The
dosing device can be battery powered, electrically powered, or hand powered. In still
yet another and/or alternative embodiment, a reservoir is provided that is designed
to at least partially hold the improved cleaning composition. In one aspect of this
embodiment, the reservoir is detachably mounted on the implement. In another and/or
alternative aspect of this embodiment, the reservoir is used in combination with a
dosing device.
[0015] In yet another and/or alternative aspect of the present invention, the improved cleaning
composition can be at least partially loaded onto an absorbent and/or adsorbent material
by a user prior to cleaning. The absorbent and/or adsorbent material can include cleaning
wipes, sponges (e.g., cellulose, synthetic, etc.), paper towels, napkins, cleaning
pads, cloths, towels, rags, mop heads, and/or the like. In such applications, the
improved cleaning composition is not preloaded or fully preloaded onto an absorbent
and/or adsorbent material, thus the cleaning composition is at least partially applied
by the user just prior to and/or during the cleaning process. When the improved cleaning
composition is used in such application, the improved cleaning composition is typically
packaged in a separate container or receptacle from the absorbent and/or adsorbent
material. During the cleaning process, the improved cleaning composition is applied
to the absorbent and/or adsorbent material. Additionally or alternatively, the cleaning
composition can be applied to the surface to be cleaned and the absorbent and/or adsorbent
material is used to pickup cleaning composition off the surface to be cleaned and/or
spread the cleaning composition on the surface to be cleaned. The improved cleaning
composition can be applied automatically and/or manually applied to the absorbent
and/or adsorbent material and/or onto the surface to be cleaned.
[0016] In still another and/or alternative aspect of the present invention, the improved
cleaning composition can be applied to a surface to be cleaned prior to exposing the
improved cleaning composition to an absorbent and/or adsorbent material. The absorbent
and/or adsorbent material can include cleaning wipes, sponges (e.g., cellulose, synthetic,
etc.), paper towels, napkins, cleaning pads, cloths, towels, rags, mop heads, and/or
the like. In such applications, the improved cleaning composition is not preloaded
onto an absorbent and/or adsorbent material, but applied by the user to a surface
to be cleaned and then wiped up by the absorbent and/or adsorbent material. The improved
cleaning composition can be applied automatically and/or manually applied to the surface
to be cleaned.
[0017] In still yet another and/or alternative aspect of the present invention, the improved
cleaning composition can be applied and/or added to a surface and/or environment to
be cleaned without every applying the cleaning composition to an absorbent and/or
adsorbent material. Examples of such uses of the improved cleaning composition include,
but are not limited to, air fresheners, shampoos, hand lotions/cleaners, cleaners
for cleaning internal components of machinery and/or process lines, carpet fresheners,
carpet cleaners, cat litter, drain cleaners, toilet cleaners, environment cleaners
(e.g., fumigation gas and/or fluid, liquid spray, etc.), and/or the like.
[0018] In still another and/or alternative aspect of the present invention, the improved
cleaning composition includes an effective amount of biocide to obtain the desired
disinfecting, sanitizing, and/or sterilizing qualities of the improved cleaning composition.
The improved cleaning composition includes one or more decides to achieve the desired

the biguanide compound content ofthe improved cleaning composition can be greater
than about 0.02 weight percent ofthe improved cleaning composition when the biguanide
compound functions as the primary biocide in the improved cleaning composition. As
can be appreciated, when other biocides are included with the biguanide compound in
the improved cleaning composition, the biguanide compound content can be lower than
about 0.02 weight percent of the improved cleaning composition. A biguanide compound
content of lower than about 0.02 weight percent, when the biguanide compound functions
as the primary biocide in the improved cleaning composition, may not eliminate a majority
of common microorganisms (e.g., bacteria, viruses, etc.) when exposed to the improved
cleaning composition. The upper limit of the biguanide compound content of the improved
cleaning composition can be significantly greaterthan about 0.02 weight percent; however,
the biguanide compound content is typically limited by economic cost considerations,
local, state and/or federal regulatory restrictions, formula solubility requirements,
streaking and residue properties of the improved cleaning composition, skin irritation
considerations, and/or the intended use of the improved cleaning composition. Typically,
the biguanide compound content of the improved cleaning composition is no more than
about 5 weight percent. A biguanide compound content that exceeds about 5 weight percent
generally results in the final product having a prohibitive cost since the biguanide
compound is typically one of the higher costing component of the improved cleaning
composition. In addition, a biguanide compound content exceeding about 5 weightpercent
may be subject to strict local, state and/or federal regulations due to the toxicity
of the improved cleaning composition. However, absent the cost and regulatory barriers,
the biguanide compound content can exceed about 5 weight percent when the improved
cleaning composition is used in applications which require a high biguanide compound
content. In this respect, the biguanide compound content can be up to or exceed about
20 weight percent of the cleaning composition. The concentration of the biguanide
compound in the improved cleaning composition may also exceed about 5 weight percent
when the improved cleaning composition is in a concentrated form, thus intended to
be diluted prior to use. In one aspect of this embodiment, the biguanide compound
content of the improved cleaning composition is about 0.05-5 weight percent. In another
aspect of this embodiment, the biguanide compound content of the improved cleaning
composition is about 0.08-5 weight percent. In still another aspect of this embodiment,
the biguanide compound content of the improved cleaning composition is about 0.1-2
weight percent. In yet another aspect of this embodiment, the biguanide compound content
ofthe improved-cleaning composition is about 0.1-1 weight percent. In still yet another
aspect of this embodiment, the biguanide compound content of the improved cleaning
composition is about 0.15-0.8 weight percent. In a further aspect of this embodiment,
the biguanide compound content of the improved cleaning composition is about 0.175-0.6
weight percent. In yet a further aspect of this embodiment, the biguanide compound
content of the improved cleaning composition is about 0.2-0.5 weight percent. In still
a further aspect of this embodiment, the biguanide compound content of the improved
cleaning composition is about 0.25-0.4 weight percent.

composition includes a cationic biocide that includes one or more quats. The cationicbiocide
in the improved cleaning composition can primarily include one or more quats, and/or

antimicrobial or germicidal properties to the improved cleaning composition. In another
and/or alternative embodiment, the general structure for the one or more quats that
can be included in the improved cleaning composition is:

embodiment, the quat content of the improved cleaning composition is greater than
about 0.04 weight percent of the improved cleaning composition when the quat functions
as the primary biocide in the improved cleaning composition. As can be appreciated,
when other biocides are included with the one or more quats in the improved cleaning
composition, the quat content can be lower than about 0.04 weight percent of the improved
cleaning composition. A quat content of lower than about 0.04 weight percent, when
the quat functions as the primary biocide in the improved cleaning composition, may
not eliminate a majority of common microorganisms when exposed to the improved cleaning
composition. The upper limit to the quat content of the improved cleaning composition
can be significantly greater than about 0.04 weight percent; however, the quat content
is typically limited by economic cost considerations, local, state and/or federal
regulatory restrictions, formula solubility requirements, streaking properties of
the improved cleaning composition, skin irritation considerations, and/or the intended
use of the improved cleaning composition. Typically, the quat content of the improved
cleaning composition is no more than about 5 weight percent. A quat content that exceeds
about 5 weight percent generally results in the final product having a prohibitive
cost since the quat is typically one of the higher costing components of the improved
cleaning composition. In addition, a quat content exceeding about 5 weight percent
may be subject to strict local, state and/or federal regulations due to the toxicity
of the improved cleaning composition. However, absent the cost and regulatory barriers,
the quat content can exceed about 5 weight percent when the improved cleaning composition
is used in applications which require a high quat content. The concentration of the
quat in the improved cleaning composition may also exceed about 5 weight percent when
the improved cleaning composition is in a concentrated form, thus intended to be diluted
prior to use. In one aspect of this embodiment, the quat content of the improved-cleaning
composition is about 0.05-5 weight percent. In another aspect of this embodiment,
the quat content of the improved cleaning composition is about 0.08-5 weight percent.
In still another aspect of this embodiment, the quat content of the improved cleaning
composition is about 0.1-2 weight percent In yet another aspect of this embodiment,
the quat content of the improved cleaning composition is about 0.1-1 weight percent.

In yet a further aspect of this embodiment, the quat content of the improved cleaning
composition is about 0.2-0.5 weight percent. In still a further aspect of this embodiment,
the quat content of the improved cleaning composition is about 0.25-0.4 weight percent.
In still another embodiment, when one or more quats are combined with one or more
biguanide compounds to function as the primary biocide in the improved cleaning composition,
the quat content is about 0.001 - 5 weight percent of the improved cleaning composition
and the biguanide compound content is also about 0.001 - 5 weight percent of the improved
cleaning composition. The specific quantities of the quat and biguanide compounds
in the improved cleaning composition is typically a function of economic cost considerations;
local, state and/or federal regulatory restrictions; formula solubility requirements;
streaking and residue properties of the improved cleaning composition; skin irritation
considerations; and/or the intended use of the improved cleaning composition. In one
specific aspect of this embodiment, the biguanide compound content is greater than
the quat content in the improved cleaning composition. In another specific aspect
of this embodiment, the biguanide compound content is less than the quat content in
the improved cleaning composition. In yet anther specific aspect of this embodiment,

in and/or used in combination with the improved cleaning composition is about 0.5
- 1.25 weight percent. In still another aspect of this embodiment, the surfactant
content in and/or used in combination with the improved cleaning composition is about
0.1 - 1 weight percent. In still yet another aspect of this embodiment, the surfactant
content in and/or used in combination with the improved cleaning composition is about
0.15 - 0.8 weight percent. In a further aspect of this embodiment, the surfactant
content in and/or used in combination with the improved cleaning composition is about
0.2 - 0.4 weight percent. In yet a further aspect of this embodiment, the surfactant
content in and/or used in combination with the improved cleaning composition is less
than about 0.5 weight percent.
[0023] In yet another and/or alternative aspect of the present invention, the improved cleaning
composition includes and/or is used in combination with an effective amount of biocide
release agent. The biocide release agent is at least partially used to increase the
amount of cationic biocide released from an absorbent and/or adsorbent material such
as, but not limited to, wipes materials, sponges (e.g., cellulose, synthetic, etc.),
paper towels, napkins, cleaning pads, cloths, towels, rags, mop heads, and/or the
like. The biocide release agent is also and/or alternatively at least partially used
to increase the amount of cationic biocide released from an absorbent and/or adsorbent
material such as, but not limited to, fabric (e.g., clothing, sheets and/or pillow
cases, blankets, quilts, stuffed animals, rugs, shoes, etc.), wood products (e.g.,
furniture, house structures, food utensils, bowls, serving platters, etc.). The biocide
release agent can be included in the cleaning composition and/or combined at a later
time with at least a portion of the improved cleaning composition. It has been found
that a significant amount of cationic biocide such as, but not limited to, biguanide
compounds and quats, are retained on an absorbent and/or adsorbent material during
use of the absorbent and/or adsorbent material during cleaning. For instance, over
about 60 percent of the biguanide compounds content in a cleaning composition and
over about 50 percent of the quat content is typically retained on a cleaning wipe
after use of the cleaning wipe. Similar retain levels of the cationic biocides occur
on various other absorbent and adsorbent materials. As a result, the cationic biocide
content of the prior cleaning solutions was typically increased to compensate for
this high retention phenomena. Consequently, the cationic biocide content was typically
at least doubled in prior cleaning solutions to ensure that the desired amount of
cationic biocide was released from the cleaning wipe. In addition, when a cationic
biocide containing cleaning solution was used in conjunction with sponges (e.g., cellulose,
synthetic, etc.), paper towels, napkins, cloths, towels, rags, mop heads, and the
like, the cationic biocide was also attracted to and retained by the sponges (e.g.,
cellulose, synthetic, etc.), paper towels, napkins, cloths, towels, rags, mop heads,
and the like, thus removing the cationic biocide from the surface to be cleaned thereby
reducing the effectiveness of prior cleaning solutions. It has been found that one
source of this retention is at least partially related to the cationic properties
of the cationic biocide and the anionic properties of the absorbent and/or adsorbent
material. Absorbent and/or adsorbent materials such as, but not limited to, cleaning
wipes, sponges (e.g., cellulose, synthetic, etc.), paper towels, napkins, cloths,
towels, rags, mop heads, and/or the like that include wood pulp, a blend of wood pulp
and/or synthetic fibers that are at least partially derived from wood pulp, include
several anionic species such as carboxylate groups, ester groups and/or the like.
These anionic species tend to bond to the cationic biocide thereby resulting in the
cationic biocide being at least partially retained on the cleaning wipe, sponges (e.g.,
cellulose, synthetic, etc.), paper towels, napkins, cloths, towels, rags, mop heads,
and the like. The biocide release agent is at least partially formulated to mitigate
or prevent this bonding phenomena thereby enabling the improved cleaning composition
to include a lower cationic biocide content without adversely affecting the cleaning
properties and/or the disinfecting, sanitizing, and/or sterilizing efficacy of the
improved cleaning composition when used in combination with an absorbent and/or adsorbent
material. The biocide release agent is at least partially formulated to mitigate or
prevent this bonding phenomena thereby enabling the improved cleaning composition
to include a lower cationic biocide content without adversely affecting the cleaning
properties, and/or the disinfecting, sanitizing, and/or sterilizing efficacy of the
improved cleaning composition. In one embodiment, the biocide release agent used with
and/or included in the improved cleaning composition includes a cationic compound
designed to at least partially compete with the cationic biocide for the anionic species
sites on an absorbent and/or adsorbent material thereby causing increased biocide
release from the absorbent and/or adsorbent material during use of the absorbent and/or
adsorbent material. The biocide release agent at least partially binds with the anionic
species sites thereby freeing the cationic biocide from the absorbent and/or adsorbent
material and allowing the cationic biocide to be freed from the absorbent and/or adsorbent
material. In another and/or alternative embodiment, the biocide release agent is at
least partially applied to an absorbent and/or adsorbent material after the cationic
biocide has been applied to the absorbent and/or adsorbent material. In one aspect
of this embodiment, the improved cleaning composition includes a biocide release agent
to at least partially compete with the cationic biocide for the anionic species sites
on an absorbent and/or adsorbent material to cause further cationic biocide release
from the absorbent and/or adsorbent. At some time after the improved cleaning composition
is applied to the absorbent and/or adsorbent material, additional biocide release
agent can be applied to the absorbent and/or adsorbent material to cause further increased
biocide release from the absorbent and/or adsorbent. In another and/or alternative
aspect of this embodiment, the improved cleaning composition substantially does not
include a biocide release agent, but such biocide release agent can be applied at
the same or subsequent time as the application of the improved cleaning composition
that includes cationic biocide. In still another and/or alternative embodiment, one
or more biocide release agents used in and/or with the improved cleaning composition
are formulated to have a higher affinity for the anionic species sites than the cationic
biocide such that the site competition between the cationic biocide and such biocide
release agent favors the biocide release agent. In one aspect of this embodiment,
the affinity of one or more biocide release agents for the anionic species sites is
significantly greater than the affinity of the cationic biocide for the anionic species
sites thereby resulting in substantially irreversible bonding of the biocide release
agent with the anionic species sites on the absorbent and/or adsorbent material. In
yet another and/or alternative embodiment, one or more biocide release agents include
a cationic salt. Salts are desirable biocide release agents in that such compounds
are generally inexpensive when compared to many types of cationic biocides. A variety
of different salts can be used such as, but not limited to, monovalent salts, divalent
salts, organic salts, and the like. These salts include, but are not limited to, acetates,
acetylides, ammonium salts (excluding quats), arsenates, astatides, azides, bihalide
salts, bicarbonates, bisulfides, borides, borohydrides, borohalides, carconates, citrates,
cyanates, cyanides, formates, germanates, glycinates, halates, halides, hydrides,
hydroselenides, hydrosulphides, hydroxides, imides, metaniobates, metaantalates, metavanadates,
nitrates, nitrides, nitrites, oxides, perchlorates, phosphates, phosphonium salts,
selenides, selenites, selenates, sulphides, sulphates, ternary salts, tetraalkyl ammonium
salts, tellurides, thiocyanates, and/or vanadates. In one aspect of this embodiment,
the biocide release agent includes, but is not limited to, potassium citrate, sodium
citrate, sodium tartrate, potassium tartrate, potassium lactate, sodium lactate, salicylate
salts of sodium and/or potassium, magnesium sulphate, sodium chloride, ammonium chloride,
and/or potassium chloride. In still yet another and/or alternative embodiment, a sufficient
amount of biocide release agent is included in and/or used with the improved cleaning
composition that includes the cationic biocide to reduce the cationic biocide retention
on an absorbent and/or adsorbent material (e.g., cleaning wipes, sponges (e.g., cellulose,
synthetic, etc.), paper towels, napkins, cloths, towels, rags, mop heads, etc.) to
less than about 50%. In one aspect of this embodiment, the improved cleaning composition
includes and/or is used with a sufficient amount of biocide release agent to reduce
the cationic biocide retention on the absorbent and/or adsorbent material to less
than about 45%. In another aspect of this embodiment, the improved cleaning composition
includes and/or is used with a sufficient amount of biocide release agent to reduce
the cationic biocide retention on the absorbent and/or adsorbent material to less
than about 40%. In still another aspect of this embodiment, the improved cleaning
composition includes and/or is used with a sufficient amount of biocide release agent
to reduce the cationic biocide retention on the absorbent and/or adsorbent material
to less than about 35%. In yet another aspect of this embodiment, the improved cleaning
composition includes and/or is used with a sufficient amount of biocide release agent
to reduce the cationic biocide retention on the absorbent and/or adsorbent material
to less than about 30%. In still yet another aspect of this embodiment, the improved
cleaning composition includes and/or is used with a sufficient amount of biocide release
agent to reduce the cationic biocide retention on the absorbent and/or adsorbent material
to less than about 25%. In a further aspect of this embodiment, the improved cleaning
composition includes and/or is used with a sufficient amount of biocide release agent
to reduce the cationic biocide retention on the absorbent and/or adsorbent material
to less than about 20%. In still a further aspect of this embodiment, the improved
cleaning composition includes and/or is used with a sufficient amount of biocide release
agent to reduce the cationic biocide retention on the absorbent and/or adsorbent material
to less than about 15%. In yet a further aspect of this embodiment, the improved cleaning
composition includes and/or is used with a sufficient amount of biocide release agent
to reduce the cationic biocide retention on the absorbent and/or adsorbent material
to less than about 10%. In still yet a further aspect of this embodiment, the improved
cleaning composition includes and/or is used with a sufficient amount of biocide release
agent to reduce the cationic biocide retention on the absorbent and/or adsorbent material
to less than about 5%. In another aspect of this embodiment, the improved cleaning
composition includes and/or is used with a sufficient amount of biocide release agent
to reduce the cationic biocide retention on the absorbent and/or adsorbent material
to less than about 3%. In still another aspect of this embodiment, the improved cleaning
composition includes and/or is used with a sufficient amount of biocide release agent
to reduce the cationic biocide retention on the absorbent and/or adsorbent material
to less than about 1%. In a further and/or alternative embodiment, the biocide release
agent is used with and/or is present in the improved cleaning composition such that
the biocide release agent has an effective ionic strength to cause a desired amount
of cationic biocide to be released from the absorbent and/or adsorbent material (e.g.,
cleaning wipes, sponges (e.g., cellulose, synthetic, etc.), paper towels, napkins,
cloths, towels, rags, mop heads, etc.). In one aspect of this embodiment, the effective
ionic strength of the biocide release agent in the improved cleaning composition and/or
used in combination with the improved cleaning composition is at least about 5 x 10
-3 mol/l. It has been found that an ionic strength of less than about 5 x 10
-3 mol/l does not result in an appreciable increase in cationic biocide release from
the absorbent and/or adsorbent material. In another aspect of this embodiment, the
effective ionic strength of the biocide release agent in the improved cleaning composition
and/or used in combination with the improved cleaning composition is about 5 x 10
-3 - 18 mol/l. In still another aspect of this embodiment, the effective ionic strength
of the biocide release agent in the improved cleaning composition and/or used in combination
with the improved cleaning composition is at least about 1 x 10
-2 mol/l. In yet another aspect of this embodiment, the effective ionic strength of
the biocide release agent in the improved cleaning composition and/or used in combination
with the improved cleaning composition is about 1 x 10
-2 - 5 mol/l. In still yet another aspect of this embodiment, the effective ionic strength
of the biocide release agent in the improved cleaning composition and/or used in combination
with the improved cleaning composition is about 2 x 10
-2 - 1 mol/l, In a further aspect of this embodiment, the effective ionic strength of
the biocide release agent in the improved cleaning composition and/or used in combination
with the improved cleaning composition is about 3 x 10
-2 - 0.4 mol/l. In yet a further aspect of this embodiment, the effective ionic strength
of the biocide release agent in the improved cleaning composition and/or used in combination
with the improved cleaning composition is about 4 x 10
-2 - 0.2 mol/l. The weight percent of the biocide release agent in the improved cleaning
composition and/or used in combination with the improved cleaning composition to achieve
a particular ionic strength in the improved cleaning composition is at least partially
a function of the molecular weight of the biocide release agent and the ionic strength
of the biocide release agent. In yet a further and/or alternative embodiment, the
biocide release agent content of the improved cleaning composition and/or the amount
of biocide release agent used in combination with the improved cleaning composition
is at least about 0.025 weight percent and can constitute up to about 90 weight percent.
In one aspect of this embodiment, the biocide release agent content of the improved
cleaning composition and/or amount of biocide release agent used in combination with
the improved cleaning composition is about 0.03 - 10 weight percent. In another aspect
of this embodiment, the biocide release agent content of the improved cleaning composition
and/or amount of biocide release agent used in combination with the improved cleaning
composition .is about 0.04 - 5 weight percent. In still another aspect of this embodiment,
the biocide release agent content of the improved cleaning composition and/or amount
of biocide release agent used in combination with the improved cleaning composition
is about 0.08 - 3 weight percent. In yet another aspect of this embodiment, the biocide
release agent content of the improved cleaning composition and/or amount of biocide
release agent used in combination with the improved cleaning composition is about
0.1 - 2.5 weight percent. In still yet another aspect of this embodiment, the biocide
release agent content of the improved cleaning composition and/or amount of biocide
release agent used in combination with the improved cleaning composition is about
0.2 - 2.5 weight percent. In a further aspect of this embodiment, the biocide release
agent content of the improved cleaning composition and/or amount of biocide release
agent used in combination with the improved cleaning composition is about 0.5 - 2
weight percent. In still a further aspect of this embodiment, the biocide release
agent content of the improved cleaning composition and/or amount ofbiocide release
agent used in combination with the improved cleaning composition is about 0.75 - 1.8
weight percent.
[0024] In still another and/or alternative aspect of the present invention, the improved
cleaning composition includes and/or is used in combination with one or more builder
detergents. The builder detergent, when used, can increase the effectiveness of the
surfactant that is used in and/or used in combination with the improved cleaning composition
when a surfactant is included in and/or used in combination with the improved cleaning
composition. The builder detergent can also function as a softener and/or a sequestering
and buffering agent when used in and/or used in combination with the improved cleaning
composition. A variety of builder detergents can be used in and/or used in combination
with the improved cleaning composition. Such builder detergents include, but are not
limited to, phosphate-silicate compounds, zeolites, alkali metal, ammonium and substituted
ammonium polyacetates, mono-, di-, and tri-alkali salts of nitrilotriacetic acid,
carboxylates, aluminosilicate materials, silicates, polycarboxylates, zeolites, carbonates,
phosphates, bicarbonates, polyphosphates, amines, alkanolamines, aminopolycarboxylates,
polyhydroxysulfonates, starch derivatives, ethylenediamine tetraacetate, and/or metal
ion sequestrants (e.g., aminopolyphosphonates such as, but not limited to, ethylenediamine
tetramethylene phosphonic acid and diethylene thiamine pentamethylenephosphonic acid).
In one embodiment, the builder detergent includes polyacetate and/or polycarboxylate
compounds. In one aspect of this embodiment, the polyacetate and/or polycarboxylate
compounds include, but are not limited to, sodium, potassium, lithium, ammonium, and
substituted ammonium salts of ethylenediamine tetraacetic acid, ethylenediamine triacetic
acid, ethylenediamine tetrapropionic acid, diethylenetriamine pentaacetic acid, nitrilotriacetic
acid, oxydisuccinic acid, iminodisuccinic acid, mellitic acid, polyacrylic acid or
polymethacrylic acid and copolymers, benzene polycarboxylic acids, gluconic acid,
sulfamic acid, oxalic acid, phosphoric acid, phosphonic acid, organic phosphoric acids,
acetic acid, and citric acid. These builder detergents can also exist either partially
or totally in the hydrogen ion form. In another and/or alternative aspect of this
embodiment, the builder detergent includes EDTA and/or EDTA salts. When EDTA salts
are included in the improved cleaning composition, the EDTA salts can contribute to
the release of the cationic biocide from the absorbent and/or adsorbent material when
the improved cleaning composition is loaded on and/or is used in combination with
the absorbent and/or adsorbent material. The cationic properties of the EDTA salts
compete for the anionic species sites on the absorbent and/or adsorbent material thereby
causing some cationic biocide to be released from the absorbent and/or adsorbent material.
Although the EDTA salts contribute to some cationic biocide release when sufficient
amounts of EDTA salts are included in the improved cleaning composition, the amount
of cationic biocide release attributable to the EDTA salts is very small due to the
low ionic strength of the EDTA salts. Consequently, EDTA salts in the improved cleaning
composition are not a substitute for the biocide release agent, and the absence of
a biocide release agent from the improved cleaning composition results in little or
no measurable reduction in cationic biocide retention from the absorbent and/or adsorbent
material. In one specific aspect, the builder agent includes sodium and/or potassium
salts of EDTA. In still another and/or alternative embodiment, the builder detergent
includes substituted ammonium salts. In one aspect of this embodiment, the substituted
ammonium salts include, but are not limited to, ammonium salts of methylamine, dimethylamine,
butylamine, butylenediamine, propylamine, triethylamine, trimethylamine, monoethanolamine,
diethanolamine, triethanolamine, isopropanolamine, ethylenediamine tetraacetic acid
and/or propanolamine. In yet another and/or alternative embodiment, the improved cleaning
composition includes and/or is used in combination with at least about 0.001 weight
percent builder detergent. In one aspect of this embodiment, the builder detergent
content in and/or used in combination with the improved cleaning composition is about
0.01 - 2 weight percent. The concentration of the builder detergent in and/or used
in combination with the improved cleaning composition may exceed about 2 weight percent
when the improved cleaning composition is in a concentrated form. In another aspect
of this embodiment, the builder detergent content in and/or used in combination with
the improved cleaning composition is about 0.01 - weight percent. In still another
aspect of this embodiment, the builder detergent content in and/or used in combination
with the improved cleaning composition is about 0.01 - 0.8 weight percent. In yet
another aspect of this embodiment, the builder detergent content in and/or used in
combination with the improved cleaning composition is about 0.05 - 0.75 weight percent.
In still yet another aspect of this embodiment, the builder detergent content in and/or
used in combination with the improved cleaning composition is about 0.05 - 0.5 weight
percent. In a further aspect of this embodiment, the builder detergent content in
and/or used in combination with the improved cleaning composition is about 0.07 -
0.3 weight percent. In still a further aspect of this embodiment, the builder detergent
content in and/or used in combination with the improved cleaning composition is about
0.09 - 0.25 weight percent.
[0025] In still another and/or alternative aspect of the present invention, the improved
cleaning composition can include and/or be used in combination with one or more solvents.
The solvent can be used to dissolve various components in the improved cleaning composition
so as to form a substantially uniformly dispersed mixture. In addition to the dispersion
and solubilizing functions of the solvent, the solvent can function as a cleaning
agent to help loosen and solubitize compounds such as greasy or oily soils from surfaces,
a residue inhibiting agent to help reduce residues left behind on a cleaned surface,
a detergent agent to assist in the detergency of the improved cleaning composition,
and/or a disinfecting, sanitizing, and/or a sterilizing agent to help eliminate various
bacteria and/or viruses on a cleaned surface. The solvent, when used, can be premixed
with the other components of the improved cleaning composition or be partially or
fully added to the improved cleaning composition after or simultaneously with use.
In one embodiment, the solvent is at least partially water soluble and/or a dispersable
organic solvent. In another and/or alternative embodiment, the solvent rapidly volatilizes.
In one aspect of this embodiment, the solvent has a vapor pressure of at least about
0.001 mm Hg at about 25° C. In another and/or alternative aspect of this embodiment,
the solvent volatilizes in no more than about 5 minutes at ambient temperature (about
25° C) after contact with a surface. In another and/or alternative embodiment, the
solvent volatilizes from a surface substantially without leaving a residue. In still
another and/or alternative embodiment, the solvent includes, but is not limited to,

ethers. In yet another and/or alternative aspect of this embodiment, the short chain
carboxylic acids include, but are not limited to, acetic acid, glycolic acid, lactic
acid and/or propionic acid. In still yet another and/or alternative aspect of this
embodiment, the short chain esters include, but are not limited to, glycol acetate,
and/or cyclic or linear volatile methylsiloxanes. In a further and/or alternative
aspect of this embodiment, water insoluble solvents such as isoparafinic hydrocarbons,
mineral spirits, alkylaromatics, terpenoids, terpenoid derivatives, terpenes, and/or
terpenes derivatives are mixed with a water soluble solvent when included in the improved
cleaning composition. When one or more water insoluble solvents are mixed with one
or more water soluble solvents in and/or used in combination with the improved cleaning
composition, the weight percentage of the water insoluble solvents in the improved
cleaning composition is generally less than about 10 weight percent, typically less
than about 5 weight percent, and more typically less than about 1 weight percent of
the improved cleaning composition. As can be appreciated, the improved cleaning composition

cleaning composition. In such a formulation, weight percentage of the water insoluble
solvent can be greater than about 10 weight percent. In one specific aspect, the water

include isopropanol and/or Dowanol PnB. In still another embodiment, the improved
cleaning composition includes and/or is used in combination with at least about 0.5
weight percent solvent when solvent is included in the improved cleaning composition.
Typically, the improved cleaning composition includes and/or is combined with at least
about 0.5 weight percent solvent to avoid solubility problems which can result from
the combination of various components of the improved cleaning composition. In one
aspect of this embodiment, the solvent content in and/or is combined with the improved
cleaning composition is about 0.5 - 70 weight percent. The concentration of the solvent
in and/or is combined with the improved cleaning composition may exceed about 70 weight
percent when the improved cleaning composition is in a concentrated form. In another

[0026] In still yet another and/or alternative aspect of the present invention, the improved
cleaning composition includes and/or is used in combination with a high and a low
boiling point solvent. As defined herein, a high boiling point solvent is a solvent
having a boiling point of at least about 150°C (302°F). As defined herein, a low boiling
point solvent is a solvent having a boiling point of less than about 150°C (302°F).
The high and low boiling point solvent is a compound other than water. Other solvents,
in addition to one solvent from each category, may be included. In another and/or
alternative embodiment, the solvents having a boiling point less than about 150°C
include, but are not limited to, methanol, ethanol, isopropanol, propanol, butyl alcohol,
sec-butyl alcohol, isobutyl alcohol, tert-butyl alcohol, pentyl alcohol, tert-pentyl
alcohol, 2-pentanol, 3-pentanol, neopentyl alcohol, ethyleneglycol methylether, ethyleneglycol
ethylether, ethyleneglycol propylether, propyleneglycol methylether, propyleneglycol

of solvent in the dual boiling point solvents used in and/or in combination with the
improved cleaning composition that have a boiling point of less than about 150°C is
generally equal to or greater than the amount of solvent having a boiling point greater

[0027] In still yet another and/or alternative aspect of the present invention, the improved
cleaning composition includes and/or is used in combination with water. The water,
when used, can be premixed with the other components of the improved cleaning composition
or be partially or fully added to the improved cleaning composition at the time of
or prior to use. The water can include tap water, filtered water, bottled water, spring
water, distilled water, deionized water, and/or industrial soft water. The amount
of water in and/or combined with the improved cleaning composition depends on whether
the improved cleaning composition is an aqueous or nonaqueous composition. In one
embodiment, the water used in and/or used in combination with the improved cleaning
composition is deionized water and/or industrial soft water. The use of deionized
water and/or industrial soft water can reduce he amount of residue formation and can
limit the amount of undesirable metal ions in and/or used in combination with the
improved cleaning composition. In another and/or alternative embodiment, the improved
cleaning composition is an aqueous composition, and the water constitutes at least
a majority weight percent of the improved cleaning composition. The amount of water
in the improved cleaning composition is typically less when the improved cleaning
composition is in a concentrated liquid or semi-liquid form, or in a solid form. In
one aspect of this embodiment, the water content in the ready to use improved liquid
cleaning composition is at least about 70 weight percent. The term "ready to use"
means the improved cleaning composition does not need to be diluted or mixed with
water and/or other solvents prior to use, or the concentrated improved cleaning composition
has been diluted with water and/or other solvents. In another and/or alternative aspect
of this embodiment, the water content in the ready to use improved liquid cleaning
composition is at least about 80 weight percent. In still another and/or alternative
aspect of this embodiment, the water content in the ready to use improved liquid cleaning
composition is at least about 90 weight percent. In yet another and/or alternative
aspect of this embodiment, the water content in the ready to use improved cleaning
composition is at least about 95 weight percent.
[0028] In a further and/or alternative aspect of the present invention, the improved cleaning
composition includes and/or is used in combination with one or more anti-dye transfer
agents. When the improved cleaning composition is used to clean and/or is used in
combination with other cleaners to clean fabrics that include dyes (e.g., clothing,
rugs, carpets, curtains, pillows, sheets and/or pillowcases, blankets, etc.), the
one or more anti-dye transfer agents in the improved cleaning composition inhibit
dry transfer during the cleaning operation. One way of overcoming the dye transfer
problem is to at least partially complex or adsorb the fugitive dyes before such dyes
have the opportunity to become attached to other articles. The anti-dry transfer agent
is formulated to provide anti-dye transfer and color protection properties to the
improved cleaning composition without adversely affecting stain or soil removal properties
and/or soil redeposition properties of the improved cleaning composition. In one embodiment,
the anti-dye transfer agent can include, but is not limited to, polyvinylpyrrolidone;
quaternary polyvinylpyrridinium derivatives; polyvinylimidazole; polyvinylpyridine
oxide; copolymers of polyvinylpyridine and polyvinylimidazole; vinyl imidazole homo-
or copolymer; polyamine oxide; vinylimidazole; vinylpyrrolidone; vinylimidazole; vinylpyridine;

on -vinylpyrrolidone and/or -vinylimidazole and/or -vinyloxazolidone; vinyloxazolidone;
and/or poly(vinylpyridine betaines). Several of these anti-dye transfer agents which
can be included in and/or used in combination with the improved cleaning composition
are disclosed in United States Patent Nos.

(e. g., Gafquat HSi, HS-100, 440, 734, 755, 755N, and/or 755N-P by ISP Corp.). The
inclusion of polyvinylpyrrolidone enhances the cleaning effectiveness of the cleaning
surfactant in the improved cleaning composition without adversely affecting the filming
and streaking properties of the improved cleaning composition. Typically, the polyvinylpyrrolidone
is a cationic polymer that is combined with a non-ionic surfactant; however, other
types of surfactants can be used in combination with the polyvinylpyrrolidone. In
yet a further and/or alternative aspect of this embodiment, the silicones include,
but are not limited to, polysicoxanes. The inclusion of silicones in the improved
cleaning composition can facilitate in enhancing the ease in which the improved cleaning
composition can be spread over a surface such as, but not limited to, a hard surface.
The increase in ease of spreading can result in the ease in which the improved cleaning
composition applied over a surface to be cleaned. The silicone can decrease the static
coefficient of friction, thereby resulting in the improved cleaning composition being
spread easer by a cleaning pad, wipe, mop, etc. In one particular example, the silicone
is a volatile silicone that evaporates upon drying without leaving surface residue
and/or a slippery surface. In another and/or alternative particular example, a suspension
polymer is used in combination with the silicone in the improved cleaning composition
to suspend the silicone in the improved cleaning composition. The suspension polymer
typically has a high enough yield stress to at least partially suspend the silicone
in the fluid improved cleaning composition. Non-limiting examples of suspension polymers

and things (e.g., rooms, pet litter, medical equipment, etc.) The improved cleaning
composition can also or alternatively be formulated for use in personal hygiene products
(e.g., hand cleaners, body lotions, shampoos, hair conditioners, etc.).
I. HARD SURFACE CLEANERS
[0052] The improved cleaning composition is particular applicable for use with hard surfaces.
Such surfaces include, but are not limited to, windows, doors, counter tops, floor,
sinks, toilets, showers, kitchen appliances, and the like. When cleaning hard surfaces,
an important goal is to not only clean, disinfect, sanitize, and/or sterilize the
hard surface, but to also reduce filming and streaking on the hard surface. It is
also desirable for the cleaned hard surface to not be sticky. The improved cleaning
composition is formulated to clean, disinfect, sanitize, and/or sterilize hard surfaces,
and to reduce filming and streaking on the hard surface without leaving a sticky surface
on the cleaned hard surface.
[0053] The improved cleaning composition can be in concentrated form or ready-to-use form.
The improved cleaning composition can be in gas, liquid, paste, gel, or solid form.
The improved cleaning composition can be dispensed from a liquid container, an aerosol
container, a container for holding crystals or a paste, and the like. The improved
cleaning composition can be preloaded onto an absorbent and/or adsorbent material,
and/or used in combination with an absorbent and/or adsorbent material.
[0054] The basic components of the improved cleaning composition for hard surfaces include:
(I) cationic biocide;
(ii) solvent and/or surfactant.
[0055] Additional components can be included in and/or used in combination with the improved
cleaning composition to add one or more attributes to the improved cleaning composition
and/or to enhance the attributes of the improved cleaning composition.
A. The Cationic Biocide
[0056] The biocide in the improved cleaning composition includes a cationic compound. The
cationic biocide typically includes one or more biguanide compounds and/or quats.
Biguanide compounds are desirable in that such compounds have a broad spectrum antimicrobial
or germicidal properties. The biguanide compounds are also less irritating to skin,
and produce less streaking and residue when applied to a hard surface. As a result,
the improved cleaning composition feels drier after being applied resulting in higher
consumer satisfaction. A variety of different biguanide compounds can be used in the
improved cleaning composition. The biguanide compounds that can be used in the improved
cleaning composition include, but are not limited to, compounds have the following
general formula:

where X
1 and X
2 are either a hydrogen or any aliphatic, cycloaliphatic, aromatic, substituted aliphatic,
substituted aromatic, heteroaliphatic, heterocyclic, and/or heteroaromatic compound.
X
1 and X
2 can be the same or different. Y
1 and Y
2 are any aliphatic, cycloaliphatic, aromatic, substituted aliphatic, substituted aromatic,
heteroaliphatic, heterocyclic, and/or heteroaromatic compound. Y
1 and Y
2 can be the same or different. M is an number equal to or greater than 1. Typically,
M has an average value such that the molecular weight biguanide compounds is about
1000-1400; however, the molecular can be higher or lower. Generally M is about 2-20.
Z
1 and Z
2 are either a hydrogen or a salt. Z
1 and Z
2 can be the same of different. In addition or alternatively, the biguanide compounds
include, but are not limited to, halogenated hexidine and its salts. One particular
nonlimiting biguanide compound that can be used in the improved cleaning composition
is Vantocil P. The biguanide compound content of the improved cleaning composition
is generally maintained at least above 0.0005 weight percent, and more generally above
about 0.02 weight percent and less than about 20 weight percent; however, higher or
lower biguanide compound contents can be used. Typically, the biguanide compound content
of the improved cleaning composition is about 0.1-0.5 weight percent. The weight percentage
range for the biguanide compound in the improved cleaning composition is selected
to disinfect, sanitize, and/or sterilize most common household, institutional, and
industrial hard surfaces. Common types of bacteria that are at least partially destroyed
by biguanide compounds in the improved cleaning composition include, but are not limited
to, Staphylococcus aureus (Staph), Kleb, Salmonella choleraesuis (Salmonella), Pseudomonas
aeruginosa, Pserratia marcescens, Influenza A2, Candida albicans, Fusarium solani,
common viruses and/or fungi.
[0057] Quats, like biguanide compounds, have a broad spectrum antimicrobial or germicidal
properties. A variety of different quats can be used in the improved cleaning composition.
The general structure for the one or more quats that can be included in the improved
cleaning composition is:

wherein X is an anion such as, but not limited to, a halide, acetate, nitrite, a lower
alkosulfate, carbonate and/or an alkyl carboxylate; and R
1 - R
4 are straight chain, branched chain and/or cyclic chain groups. R
1 - R
4 can be the same or different. Nonlimiting types of quat that can be used in the improved
cleaning composition include an alkyldimethylbenzylammonium quat, an alkyldimethylethylbenzylammonium
quat and/or an alkyldimethylammonium quat. Nonlimiting specific quat that can be used
in the improved cleaning composition is a combination of alkyldimethylbenzylammonium
chloride (C
14 - 60%, C
16 - 30%, C
12 - 5%, C
18 - 5%) and alkyldimethylethylbenzylammonium chloride (C
12 - 68%, C
14 - 32%); alkyldimethylbenzyl ammonium chlorides such as the commercially available
Barquat MB-50 from Lonza; di(C6-C14)alkyl di(C 1-4 alkyl and/or hydroxyalkl) quaternary
ammonium compounds such as Bardac 2050 and/or 2250 from Lonza, (3-chloroallyl) hexaminium
chlorides such as Dowicide and Dowicil available from Dow; benzethonium chloride such
as Hyamine from Rohm & Haas, methylbenzethonium chloride represented by Hyamine IOX
supplied by Rohm & Haas, cetylpyridinium chloride such as Cepacol chloride available
from of Merrell Labs. This quat combination is commercially available as Barquat 4250
and Barquat 4250Z by Lonza. When one or more quats are included in the improved cleaning
composition, the quat content of the improved cleaning composition is typically maintained
above about 0.0005 weight percent and less than about 20 weight percent; however,
higher or lower quat contents can be used. Generally, the quat content ofthe improved
cleaning composition is less than or equal to the content of the biguanide compound
in the improved cleaning composition, when biguanide compounds are included in the
improved cleaning composition; however, the quat content can be greater than the biguanide
compound content. The weight percentage range for the quat in the improved cleaning
composition is selected to disinfect, sanitize, and/or sterilize most common household,
institutional, and industrial hard surfaces. Common types of bacteria that are at
least partially destroyed by the quat in the improved cleaning composition include,
but are not limited to, Staphylococcus aureus (Staph), Kleb, Salmonella choleraesuis
(Salmonella), Pseudomonas aeruginosa, Pserratia marcescens, Influenza A2, Candida
albicans, Fusarium solani, common viruses and/or fungi.
B. The Solvent
[0058] The solvent used in and/or in combination with the improved cleaning composition
is selected to at least partially dissolve into solution the biguanide compound, quat,
and/or other organic compounds in the improved cleaning composition. The use of certain
solvents can also improve the cleaning, biocidal and/or detergency properties of the
improved cleaning composition. Typically, the solvent is water soluble and rapidly
volatilizes substantially without leaving a residue, causing streaking, and/or leaving
a sticky surface. The solvent also typically has a vapor pressure of at least about
0.001 mm Hg at about 25° C, and volatilizes in no more than about 5 minutes at ambient
temperature (about 25°C) after contact with a surface.
[0059] Generally, the one or more solvents include in and/or used in combination with the
improved cleaning composition include, but are not limited to, C
1-6 alkanols, C
1-6 diols, C
1-10 alkyl ethers of alkylene glycols, C
3-24 alkylene glycol ethers, and/or polyalkylene glycols. The solvent content of the improved
cleaning composition is generally maintained above about 0.1 weight percent and generally
less than about 10 weight percent; however, higher or lower solvent contents can be
used. Typically, the solvent content of the improved cleaning composition is about
0.5 - 5 weight percent. The lower solvent weight percentages are especially desirable
in jurisdictions wherein regulations require solvent concentrations of less than about
4-10 weight percent in the improved cleaning composition.
[0060] Various solvent combinations in the improved cleaning composition can also facilitate
in the reduction of filming and/or streaking. One particular solvent combination that
results in reduced filming and/or streaking is a solvent combination that includes
a high and a low boiling point solvent combination. As can be appreciated, the improved
cleaning composition does not require the use of such a solvent combination. In addition,
when two of more solvents are included in the improved cleaning composition, all the
solvents can be high or low boiling point solvents. However, the present invention
contemplates the added improvement of using a high and a low boiling point solvent
in the improved cleaning composition. Solvents having a boiling point of less than
about 150°C that can be used in the improved cleaning composition include, but are
not limited to, methanol, ethanol, isopropanol, propanol, butl alcohol, sec-butyl
aloohol, isobutyl alcohol, tert-butyl alcohol, pentyl alcohol, tert-pentyl alcohol,
2-pentanol, 3-pentanol, neopentyl alcohol, allyl, crotyl, methylvinyl-carbinol, ethyl
ether, -propyl ether, isopropyl ether,-butyl ether, vinyl ether, allyl ether, ethyleneglycol
methylether, ethyleneglycol ethylether, ethyleneglycol propylether, propyleneglycol
methylether, propylene glycol ethylether, ethyleneglycol methyletheracetate, and/orpropyleneglycol
methyletheracetate. Solvents having a boiling point greater than or equal to about
150°C that can be used in the improved cleaning composition include, but are not limited
to, ethylene glycol, propylene glycol, butanediol, methylpropanediol, ethyleneglycol
butylether, ethyleneglycol hexylether, ethyleneglycol ethylhexylether, diethyleneglycol
methylether, diethyleneglycol ethylether, diethyleneglycol propylether, diethyleneglycol
butylether, propyleneglycol-propylether, propyleneglycol t-butylether, propyleneglycol
-butylether, dipropyleneglycol methylether, dipropyleneglycol ethylether, dipropyleneglycol
propylether, dipropyleneglycol t-butylether, dipropyleneglycol -butylether, tripropyleneglycol
methylether, tripropyleneglycol -butylether, ethyleneglycol ethyletheracetate, propyleneglycol
ethyletheracetate, ethyleneglycol butyletheracetate, propyleneglycol butyletheracetate,
diethyleneglycol methyletheracetate, dipropyleneglycol methyletheracetate, diethyleneglycol
ethyletheracetate, dipropyleneglycol ethyletheracetate, diethyleneglycol butyletheracetate,
dipropyleneglycol butyletheracetate, and/or N-methyl-2-pyrrolidone.
[0061] The amount of solvent in the dual boiling point solvents having a boiling point less
than about 150°C is generally equal to or greater than the solvent having a boiling
point greater than or equal to about 150°C.
C. The Surfactant
[0062] The surfactant used in and/or in combination with the improved cleaning composition
is selected to improve the cleaning performance of the improved cleaning composition.
The surfactant can also reduce the amount of perceived filming and/or streaking of
the improved cleaning composition. The surfactant also can provide detergency to the
improved cleaning composition to facilitate in the removal of soil from the hard surface.
The surfactant also can reduce the amount of redeposition of soils onto the hard surface.
[0063] Generally the surfactant includes, but is not limited to, at least one lauryl sulfate,
laurylether sulfate, cocamidopropylbetaine, alkyl polyglycoside, ethoxylated alcohol,
fluorosurfactant, and/or amine oxide. In one particular formulation, the surfactant
in and/or used in combination with the improved cleaning composition includes alkyl
polyglycosides, ethoxylated alcohol, fluorosurfactant and/or amine oxides. One particular
not limiting example of alkyl polyglycosides, ethoxylated alcohol, fluorosurfactant
and/or amine oxides that can be included in the improved cleaning composition are
amine oxides sold under the brand Barlox by Lonza, alkyl polyglycosides sold under
the brand APG by Cognis, ethoxylated alcohol sold under the Surfonic by Huntsman,
and/or fluorosurfactant sold under the brand Zonyl by DuPont. The surfactant content
in and/or used in combination with the improved cleaning composition is generally
at least about 0.001 weight percent of the improved cleaning composition, typically
at least about 0.05 weight percent and less than about 10 weight percent of the improved
cleaning composition, and more typically about 0.06-2 weight percent of the improved
cleaning composition.
D. The Absorbent and/or Adsorbent Material
[0064] The improved cleaning composition, when used to clean hard surfaces, is generally
used in conjunction with one or more absorbent and/or adsorbent materials. The improved
cleaning composition can be sprayed and/or poured onto a hard surface to be cleaned
and an absorbent and/or adsorbent material such as, but not limited to, a sponge,
mop head, cloth, towel, and the like is then used to spread the improved cleaning
composition on the hard surface and/or clean the hard surface. Additionally or alternatively,
the improved cleaning composition is at least partially loaded on the absorbent and/or
adsorbent material prior to the absorbent and/or adsorbent material at least partially
applying the improved cleaning composition onto the hard surface and/or cleaning the
hard surface.
[0065] The present invention also contemplates the pre-loading of the improved cleaning
composition on a cleaning pad and/or cleaning wipe. The cleaning pad or cleaning wipe
typically includes wood pulp and/or wood pulp derivatives; however, this is not required.
The improved cleaning composition on the cleaning pad or cleaning wipe is typically
in a ready to use liquid form; however, the improved cleaning composition can be in
a concentrate in liquid, semi-liquid or solid form on the cleaning pad or cleaning
wipe. Typically, the cleaning wipe has at least one layer of nonwoven material. The
cleaning pad can also included one or more layers of nonwoven material. Nonlimiting
examples of commercially available cleaning wipes that can be used include DuPont
8838, Dexter ZA, Dexter 10180, Dexter M10201, Dexter 8589, Ft. James 836, and Concert
STD60LN. All of these cleaning wipes include a blend of polyester and wood pulp. Dexter
M10201 also includes rayon, a wood pulp derivative. The cleaning pad or cleaning wipe
can be used by-itself and/or in combination with another device such as, but not limited
to, a mop. The cleaning pad typically has an absorbent capacity, when measured under
a confining pressure of 0.09 psi after 20 minutes, of at least about 1 g deionized
water per g of the cleaning pad. The cleaning pad will also typically have a total
fluid capacity (of deionized water) of at least about 100 g. However, the absorbency
and/or fluid capacity of the cleaning pad can vary depending on the desired use of
the cleaning pad. The cleaning wipe can have the same or different amount of absorbency.
[0066] The cleaning wipe or pad can contain a superabsorbent material to enhance the absorbency
and/or fluid capacity of the cleaning pad or cleaning wipe. When superabsorbent material
is included in the cleaning pad or cleaning wipe, the cleaning pad or cleaning wipe
will typically comprise at least about 1% by weight of the cleaning pad or cleaning
wipe, and more typically at least about 5%.
[0067] The cleaning pad or cleaning wipe can also include materials to stiffen the cleaning
pad or' cleaning wipe. Such materials include, but are not limited to, chemically
stiffened cellulosic fibers.
[0068] The cleaning pad or cleaning wipe can also include a thermoplastic material to at
least partially bind together the adsorbent and/or adsorbent fibers in the cleaning
pad or cleaning wipe. The thermoplastic material can also enhance the integrity of
the cleaning pad or cleaning wipe.
[0069] The loading ratio of the improved cleaning composition onto the cleaning wipe or
cleaning pad can be about 2-5:1, and typically about 3-4:1; however, other loading
rations can be used. The improved cleaning composition can be loaded onto the cleaning
wipe and/or cleaning pad in any number of manufacturing methods. Typically, the cleaning
wipe or cleaning pad is soaked in the improved cleaning composition for a period of
time until the desired amount of loading is achieved.
[0070] The cleaning pad or cleaning wipe can also have an attachment layer that allows the
cleaning pad or cleaning wipe to be connected to and/or disconnected from an implement's
handle or the support head or an implement (e.g., mop, broom, etc.). The attachment
layer can also function to prevent fluid flow through the top surface (e.g., the handle-contacting
surface) of the cleaning pad or cleaning wipe, and/or can further provide enhanced
integrity for the cleaning pad or cleaning wipe.
[0071] The cleaning pad or cleaning wipe can also be part of a cleaning kit. The kit can
have an assembly of one or more units, either packaged together or separately. The
kit can comprise an implement containing a cleaning pad or cleaning wipe that may
or may not include a superabsorbent material, and the improved cleaning composition.
The cleaning pad or cleaning wipe can be detachably mounted on the implement so that
the cleaning pad or cleaning wipe can be removed and/or replaced with a fresh clean
pad or cleaning wipe. The implement can also include a dosing device that delivers
the improved cleaning composition on the cleaning pad or cleaning wipe and/or on the
hard surface to be cleaned. The dosing device can be battery powered, electrically
powered, or hand powered. The implement can also have a reservoir that contains the
improved cleaning composition. The reservoir can be refillable or contain a non-refillable
amount of improved cleaning composition. The reservoir can also be detachably mounted
on the implement to allow for easy refilling or replacing with a filled reservoir.
E. Water
[0072] The improved cleaning composition typically includes water. When the improved cleaning
composition is a liquid, water based, ready-to-use cleaner, the water content of the
improved cleaning composition is generally over 50 weight percent of the improved
cleaning composition. Typically, the liquid ready-to-use improved cleaning composition
includes at least about 80 weight percent water; however, higher or lower water contents
can be used. When the improved cleaning composition is a liquid, non-water based,
ready-to-use cleaner, the water content of the improved cleaning composition is generally
less than about 30 weight percent of the improved cleaning composition, and typically
less than about 15 weight percent ofthe improved cleaning composition. The water used
in the improved cleaning composition is typically deionized water and/or industrial
soft water so as to reduce residue formation and limit the amount of undesirable metal
ions in the improved cleaning composition; however, other types of water can be used
(e.g., tap water, spring water, filtered water, etc.).
F. Biocide Release Agent
[0073] When the improved cleaning composition is loaded onto an absorbent or adsorbent material,
and/or is to be used with an absorbent or adsorbent material, a biocide release agent
is typically included in and/or used with the improved cleaning composition to improve
the release of the biguanide compound, quat, and/or other cationic biocides in the
improved cleaning composition from the absorbent and/or adsorbent material. The biocide
release agent used in the improved cleaning composition typically includes a cationic
compound designed to compete with the cationic biocide (e.g., biguanide compound,
quat, etc.) for anionic species sites on the absorbent and/or adsorbent material (e.g.,
sponges (e.g., cellulose, synthetic, etc.), paper towels, cleaning pads, cleaning
wipes, napkins, cloths, towels, rags, mop heads, squeegee). The cationic biocide release
agent typically includes a cationic salt. Generally, a commonly available salt is
used so as to minimize the raw material cost of the improved cleaning composition.
In addition, a salt having a relatively high ionic strength per mole of salt is selected
to minimize the amount of salt needed in the improved cleaning composition so as to
also minimizing the raw material cost of the improved cleaning composition. Nonlimiting
examples of salts that can be used as a biocide release agent in and/or in combination
with the improved cleaning composition include potassium citrate, sodium citrate,
magnesium sulphate, sodium chloride, ammonium chloride, and/or potassium chloride.
Generally, the one or more salts are added to and/or used in combination with the
improved cleaning composition in an amount to cause over about 50% of the cationic
biocide to be released from the an absorbent or adsorbent material when used to clean
a hard surface. Generally, the ionic strength of the one or more salts that make up
the biocide release agent used in and/or used in combination with the improved cleaning
composition is about 1 x 10
-2 - 2 mol/l, and the weight percent of the salt used in and/or in combination with
the improved cleaning composition is about 0.04 - 5 weight percent.
G. Additional Anti-Microbial Compound
[0074] One or more additional anti-microbial compounds can be included in and/or used in
combination with the improved cleaning composition to enhance the biocidal efficacy
of the improved cleaning composition. Such anti-microbial compounds include, but are
not limited to, diisobutylphenoxyethoxyethyl dimethylbenzyl ammonium chloride, commercially
available as Hyamine 1622 from Lonza. Other anti-microbial compounds include, but
are not limited to, alcohols, peroxides, boric acid and borates, chlorinated hydrocarbons,
organometallics, halogen-releasing compounds, mercury compounds, metallic salts, pine
oil, essential oils, organic sulfur compounds, iodine compounds, silver nitrate and
other silver compounds, quaternary phosphate compounds, and/or phenolics.
H. Polymer
[0075] Various types of polymers can also be included in and/or used in combination with
the improved cleaning composition. These polymers are typically added to the improved
cleaning composition to enhance the detergency of the improved cleaning composition,
improved wetting of the improved cleaning composition, and/or reduce filming and/or
streaking of the improved cleaning composition. The polymers, when used, include,
but are not limited to, polysaccharides, polycarboxylates, polystyrenesulfonates,
acrylate polymers, polyethyleueimines, polyvinylpyrrolidones, polymethylvinyl ether,
polyvinyl alcohols, silicones, polyethylene glycols, and/or copolymers thereof. Polymers
that have improved the detergency of the improved cleaning composition include, but
are not limited to a copolymer of vinylpyrrolidone and dimethylaminoethylmethacrylate
quaternized with diethylsulfate (e.g., Gafquat HSi, HS-100, 440, 734, 755, 755N, and/or
755N-P by ISP Corp.), and/or quaternary acrylic copolymer (e.g., Syntran HX52-1-1
(Interpolymer)). The inclusion of these polymers has been found to enhance the cleaning
effectiveness of the cleaning surfactant (e.g., alkylpolyglucosides, etc.) in the
improved cleaning composition without significantly adversely affecting the filming
and streaking properties of the improved cleaning composition.
I. Buffer/ Builder
[0076] A builder detergent can be included in and/or be used in combination with the improved
cleaning composition. The builder detergent, when used, typically increases the detergency
effectiveness of the surfactant in the improved cleaning composition. The builder
detergent can also or alternatively function as a softener, a sequestering, and/or
buffering agent in the improved cleaning composition. A variety of builder detergents
can be used in the improved cleaning composition.
J. Additional Adjuvants
[0077] The improved cleaning composition can includes and/or be used in combination with
one or more additional adjuncts. The adjuncts include, but are not limited to, fragrances
or perfumes, waxes, dyes and/or colorants, solubilizing materials, stabilizers, thickeners,
de foamers, hydrotropes, lotions and/or mineral oils, enzymes, bleaching agents, cloud
point modifiers, and/or preservatives.

hard surface cleaning is as follows:
Cationic Biocide |

[0113] When a biocide release agent is used in and/or is used in combination with the improved
cleaning composition, the biocide release agent positively affects the release of
cationic biocide from an absorbent and/or adsorbent material. As illustrated in Table
1, and in FIGURE 1, the increase in salt content (e.g., biocide release agent) in
the improved cleaning composition results in a decreased quat retention on the absorbent
and/or adsorbent material (e.g. cleaning wipe) and an increase in quat recovery. Similar
results were obtained when biguanide compounds were included in the improved cleaning
composition as illustrated in Table 2 and in FIGURE 2.
[0114] In obtaining the results set forth in Table 2, the improved cleaning composition
that included quat and was loaded on a cleaning wipe, and several trials were conducted
using two types of cleaning wipes and five different types of biocide release agent.
The quat used in the improved cleaning composition was BARQUAT 4250Z by Lonza. The
improved cleaning composition included about 0.29 weight percent biocide, about 0.3
weight percent amine oxide, about 0.1 weight percent sodium EDTA, 4.9 weight percent
isopropanol, and the balance water. Each cleaning wipe had a loading ratio of improved
cleaning composition to cleaning wipe of about 3.75:1.

[0115] The improved cleaning composition that included biguanide compounds and was also
loaded on a cleaning wipe, and a single trial was conducted using Dexter 8589 for
the cleaning wipe and Vantocil P (PHMB) by Avecia for the biguanide compound. The
improved cleaning composition included about 0.3 weight percent biguanide compound,
about 0.5 weight percent APG, 2.6 weight percent isopropanol, about 1 weight percent
Dowanol PnB, and the balance water. The cleaning wipe had a loading ratio of improved
cleaning composition to cleaning wipe of about 3.75: 1. The results of the test are
illustrated in Table 2.

[0116] As illustrated in Tables 1 and 2, the quat and Biguanide compound retention on the
cleaning wipe is about 50% and 64% respectively when the biocide release agent was
not included in the improved cleaning composition. The results in Tables 1 and 2 illustrate
that the quat and biguanide compound retention is substantially reduced by increasing
the concentration of biocide release agent in the improved cleaning composition. The
variances in measured quat and biguanide compound retention are believed to be due
to the type of cleaning wipe used, the ionic strength of the biocide release agent,
and/or the chemical structure of the quat or biguanide compound. In every test, the
inclusion of the biocide release agent in the improved cleaning composition resulted
in an increased quat and biguanide compound release from the cleaning wipe. FIGURE
1 graphically illustrates the quat retention on a DuPont 8838 cleaning wipe as a function
of the biocide release agent content of the improved cleaning composition. FIGURE
2 graphically illustrates the biguanide compound retention on a Dexter 8589 cleaning
wipe as a function of the biocide release agent content of the improved cleaning composition.
[0117] Another set of tests were conducted to determine if there was any effect on the quat
release levels from the cleaning wipe as a function of the type of cleaning wipe.
The results of these tests are illustrated in Table 3. The cationic biocide used in
the improved cleaning composition illustrated in Table 3 was BARQUAT 4250Z by Lonza.
The improved cleaning composition included about 0.29 weight percent cationic biocide,
about 0.3 weight percent amine oxide, about 0.1 weight percent sodium EDTA, about
4.9 weight percent isopropanol, and the balance water. The biocide release agent used
was potassium citrate. Two concentrations of potassium citrate were used in the improved
cleaning composition. The cleaning wipe was DuPont 8838 having a loading ratio of
improved cleaning composition to cleaning wipe of about 3.75:1.

[0118] The test results in Table 3 reveal that an increase in quat release from the cleaning
wipe occurred regardless of the type of wood pulp containing cleaning wipe. Similar
results were observed from cleaning compositions containing biguanide compounds. In
addition, the test results conformed that increased biocide release agent concentrations
in the improved cleaning composition resulted in decreased quat and biguanide compound
retention on the wipe.
[0119] Another set of tests were conducted to determine if there was any affect on the amount
of quat or biguanide compound release as a function of the amount of quat or biguanide
compound in the improved cleaning composition. The results of these tests are illustrated
in Table 4. The cationic biocide used in the improved cleaning composition illustrated
in Table 4 was BARQUAT 42502 by Lonza. The improved cleaning composition included
about 0.3 weight percent amine oxide, about 1 weight percent potassium citrate, about
0.1 weight percent sodium EDTA, about 4.9 weight percent isopropanol, and the balance
water. The cleaning wipe was DuPont 8838 having a loading ratio of improved cleaning
composition to cleaning wipe of about 3.75:1.

[0120] The results in Table 4 indicate that the amount of quat compound released from the
cleaning wipe is not adversely affected by the amount of quat in the improved cleaning
composition. Similar results were observed from cleaning compositions containing biguanide
compounds.
[0121] Several tests were also conducted to determine whether the biocide release agent
in the cleaning agent adversely affected the bactericidal efficacy of the improved
cleaning composition containing quat and/or biguanide compound. In each test conducted,
the biocide release agent did not adversely affect the bactericidal efficacy of the
improved cleaning composition. In addition, it was found that the biocide release
agent alone had little or no bactericidal efficacy.
[0122] Micro efficacy data was also obtained for an improved cleaning composition containing
a quat and an improved cleaning composition containing a biguanide compound. These
two formulations were compared to Lysol cleaner and Mr. Clean, both commercially available
products. The results are set forth in Table 5.

[0124] As illustrated in Table 5, both Clorox formulas exhibit excellent micro efficacy
properties. The micro efficacy properties where as good as or better than the tested
commercially available products.
[0125] Tests were also conducted to determine the cleaning effectiveness of the improved
cleaning composition. Two different sets of data were collected for determining the
cleaning effectiveness of the improved cleaning composition, namely filming and streaking
data, and soil removal data. Two different Clorox formulations were used when testing
the soil removal effectiveness of the formulations, and three Clorox formulations
were used when testing the filming and streaking properties of the formulations. These
formulations were also successfully used on a variety of absorbent and/or adsorbent
materials (e.g. wipes, mop heads, sponges, towels, etc.). Clorox Q and Q1 are quat
containing formulations. Clorox B is a biguanide compound containing formulation.
In each test, the Clorox formulations were compared to Mr. Clean and Lysol cleaners.
The test results of these data sets are shown in Tables 6 and 7.

[0126] As illustrated in Table 6, both Clorox formulations effectively removed a variety
of different soils from a hard surface. The number values in Table 6 represent the
area under a curve. The larger the area under the curve, the cleaner the surface that
was cleaned. In other words, the higher the number, the better the cleaning. Both
Clorox formulations out performed the Lysol cleaner in each soil test. Both Clorox
formulations also cleaned the Sanders & Lambert soil and kitchen grease soil as well
as or better than Mr. Clean. Mr. Clean had better cleaning results for the bathroom
soil. In each test, Clorox B slightly outperformed Clorox Q except in the bathroom
soil test where Clorox B was significantly better than Clorox Q. Although Mr. Clean
performed slightly better than the Clorox formulations in certain soil tests, Mr.
Clean did not effectively sanitize or sterilize the cleaned surface as illustrated
in Table 5. Therefore, the results in Table 6 illustrate that the Clorox formulations
are a significant improvement over prior cleaning compositions in that the Clorox
formulations effective clean a variety of soils and also sanitize or sterilize such
cleaned surface. Neither Mr. Clean or Lysol exhibit such properties.
[0127] The Clorox formulations also exhibited excellent filming and streaking characteristics.
Clorox B had the best filming and streaking characteristics. Clorox Q and Q1 had filming
and streaking characteristics that were similar to Lysol. Mr, Clean exhibited by far
the most filming and streaking of the cleaners tested. The significantly reduced filming
and streaking of Clorox B is believed to be the result of the special combination
of biguanide compound and surfactant, or biguanide compound, surfactant and solvent
in the improved cleaning composition. The specific Biguanide compound used in Clorox
B was Vantocil P; however, it is believed that other Biguanide compounds will produce
similar results. The surfactant used in Clorox B was a polyglucoside, specifically
an aklypolyglucoside. The solvent included a lower alcohol and PnB. The combination
of a quart with a polyglucoside, lower alcohol and PnB was also tested in Clorox Q1,
but did not yield a F&S score that was nearly as low as the biguanide compound formulation
of Clorox B. The general formulation for Clorox Q1 is set forth as follows:

[0128] Another set oftests were conducted to ascertain the dennal irritancy of the improved
cleaning compositions. Three Clorox formations were used. These formulations were
also successfully used on a variety of absorbent and/or adsorbent materials (e.g.
wipes, mop heads, sponges, towels, etc.). Clorox Q and Q2 include about 0.2 weight
percent quat and Clorox B included about 0.3 weight percent biguanide compound. The

[0130] The test results reveal that Clorox B, which included a higher concentration of biguanide
compound than the concentration of quat in Clorox Q and Q2, exhibited lower mean dermal
irritation scores that the two quat containing formulations. These unanticipated results
reveal that the biguanide compound containing formulations induce significantly less
dermal irritation without compromising the cleaning and sanitizing or sterilizing
properties of the improved cleaning composition. As a result, the biguanide compound
containing formulations can be used in a wider range of applications, especially where
skin irritation is of concern.
[0131] Several formulations for the improved cleaning composition were tested to determine
the benefit of adding a polymer to the improved cleaning composition. These formulations
were successfully used on a variety of absorbent and/or adsorbent materials (e.g.
wipes, mop heads, sponges, towels, etc.). The polymer used in this series of tests
was Gafquat 440. The tests revealed that the improved cleaning composition that included
a polymer resulted in improved detergency. The formulations of the improved cleaning
composition and the Sanders & Lambert scores are set fort in Table 9.

[0132] The results of the Sanders & Lambert test reveal that the addition of Gafquat 440
to the improved cleaning composition significantly improved the cleaning performance
of the improved cleaning composition. Further testing revealed a noticeable detergency
performance increase in the improved cleaning composition when the improved cleaning
composition included at least about 0.02 weight percent Gafquat. Gafquat contents
as high as 10 weight percent also produced improved the cleaning performance of the
improved cleaning composition. Concentrations that exceeded about 10 weight percent
resulted in increased filming and streaking of the improved cleaning composition.
Testing also revealed that the combination of Gafquat and APG resulted in improved
detergency. APG, a surfactant, provided detergency to the improved cleaning composition
without the inclusion of the Gafquat. However, the detergency of the improved cleaning
composition was significantly enhanced when Gafquat was added in combination with
APG to the improved cleaning composition. Similar improvements in detergency were
also realized by the inclusion of other polymers in the improved cleaning composition.
Several of these polymers are identified in Tables 10 and 11. Generally, the weight
percent of APG in the improved cleaning composition is about 0.02 - 5%.
[0133] Additional tests were conducted to compare the use of various types of polymers in
combination with detergency surfactants such as APG. These formulations were also
successfully used on a variety of absorbent and/or adsorbent materials (e.g. wipes,
mop heads, sponges, towels, etc.). The test results are set forth in Table 10.

[0134] The results from Table 10 reveal that polymers other than Gafquat effectively work
in combination with detergency surfactants to significantly improved the detergency
of the improved cleaning composition. The results in Table 10 also reveal that the
addition of a fluorosurfactant such as Zonyl FSO can also improve the detergency of
the improved cleaning composition. As shown in Formulation L, the improved cleaning
composition is absent polymer and fluorosurfactant. The Sanders & Lambert score for
Formulation L was the lowest of the test formulations. An increase in the Sanders
& Lambert score was obtained by adding a polymer to the improved cleaning composition
as shown in Formulation M. The inclusion of fluorosurfactant in several of the formulations
resulted in a significant increase in the Sanders & Lambert score.
[0135] Table 11 illustrates several formulations for the improved cleaning composition that
were used in combination with a cleaning wipe and other types of absorbent and/or
adsorbent materials, and which provided effective contact disinfection on hard surfaces
such as tiles. These formulations also resulted in effective detergency of the improved
cleaning composition.

[0141] The formulations of the improved cleaning composition illustrated in Table 14 were
compared to two different Lysol products. All of the tested formulations were applied
to black tile, and tested for filming/streaking using an absorbent pad. These formulations
were successfully used on a variety of absorbent and/or adsorbent materials (e.g.
wipes, mop heads, sponges, towels, etc.). The results of the test reveal the benefit
of using a dual solvent system in the improved cleaning composition, with or without
polymer.
II. OTHER TYPES OF CLEANERS
[0142] The improved cleaning composition is particularly applicable for use with hard surfaces;
however, the improved cleaning-composition can be formulated for use in other types
of cleaners. As can be appreciated, the various applications for the improved cleaning
composition include, but are not limited to, domestic and industrial applications.
Several applications include, but are not limited to, power wash solutions, deck cleaners;
vehicle cleaners, house siding cleaners; fire arm cleaners; and the like. Depending
on the particular application for the improved cleaning composition, the cleaning
composition can be formulated to disinfect, sanitize, and/or sterilize. As can be
appreciated, the improved cleaning composition can be used in many other types of
applications that require cleaning, and disinfecting, sanitizing, and/or sterilizing
of a surface.
[0143] As with hard surface formulations, the improved cleaning composition can be in concentrated
form or ready-to-use form. The improved cleaning composition can be in gas, liquid,
paste, gel, or solid form. The improved cleaning composition can be dispensed from
a liquid container, an aerosol container, a container for holding crystals or a paste,
and the like. The improved cleaning composition can be preloaded onto an absorbent
and/or adsorbent material.
[0144] The basic components of the improved cleaning composition when used other applications
include:
(I) cationic biocide; and,
(ii) surfactant and/or biocide release agent.
[0145] The cationic biocide, surfactant, and/or biocide release agent used in the improved
cleaning composition can be the same or similar compounds used in the improved cleaning
composition for hard surfaces. The cationic biocide (e.g., biguanide compound, quat,
etc.) in the improved cleaning composition is used at least in part to enhance the
disinfecting, sanitizing, and/or sterilizing attributes of the improved cleaning composition.
The biocide release agent in the improved cleaning composition is used at least in
part to reduce or prevent the retention of the cationic biocide on an absorbent and/or
adsorbent surface.
[0146] The improved cleaning composition can also include buffering and pH adjusting agents,
fragrances or perfumes, waxes, dyes and/or colorants, solubilizing materials, stabilizers,
thickeners, defoamers, hydrotropes, lotions and/or mineral oils, enzymes, bleaching
agents, cloud point modifiers, preservatives, ion exchangers, alkalies, anticorrosion
materials, antiredeposition materials, optical brighteners, chelating agents, enzymes,
whiteners, brighteners, antistatic agents, sudsing control agents, hydrotropes, bleach
precursors, soil removal agents, anti-dye transfer agents, soil release agents, softening
agents, opacifiers, inert diluents, graying inhibitors, stabilizers, and/or polymers.
[0147] A one general formulation of the improved cleaning composition in weight percent
is as follows:
Cationic Biocide |
0.02 - 20% |
Biocide Release Agent |
0.025 - 90% |
Water |
less than about 99.95% |
wherein the ionic strength of the biocide release agent is at least about 5 x 10
-3 mol/l.
[0148] Another general formulation of the improved cleaning composition in weight percent
is as follows:
Cationic Biocide |
0.02 - 20% |
